[T6] Set the max fps limit to 250 or 333

Feature: com_maxfps 250 or com_maxfps 333
Description: The stock max fps limit of 200 seems to be bugged on Windows 10 PCs. It stuters around 170-180, making the game feel quite laggy compared to Windows 7's stable 200 fps.
Motivation: This feature should be added to the client, so people with a 144 Hz screen can have a less laggy experience. And 240 Hz screen owners would also benefit from this.
